Answer:
![r=-6](https://tex.z-dn.net/?f=r%3D-6)
Step-by-step explanation:
First, we need to subtract 6 from each side, so that we can begin to isolate r.
![18=6-2r\\\\12=-2r](https://tex.z-dn.net/?f=18%3D6-2r%5C%5C%5C%5C12%3D-2r)
Next, we can divide each side by -2
![12=-2r\\\\\frac{12}{-2} =\frac{-2r}{-2} \\\\-6=r](https://tex.z-dn.net/?f=12%3D-2r%5C%5C%5C%5C%5Cfrac%7B12%7D%7B-2%7D%20%3D%5Cfrac%7B-2r%7D%7B-2%7D%20%5C%5C%5C%5C-6%3Dr)
Answer:
(0,0), (0,1), (1,2), (1,3)
Step-by-step explanation:
To determine what makes ordered pairs a function, we have to make sure each input (x) goes to exactly one output (y).
The reason this is the answer is that each input doesn't have exactly one output. (0 goes to 0 and 1. 1 goes to 2 and 3).
Two angles are complementary if they sum to 90°. So, if one angle is 55, the other angle must be such that
![55+x=90](https://tex.z-dn.net/?f=55%2Bx%3D90)
Similarly, two angles are supplementary if they sum to 180°. So, if one angle is 10, the other angle must be such that
![10+x=180](https://tex.z-dn.net/?f=10%2Bx%3D180)
